Gmail and Yahoo (SSL encryption) emails fail to send and just hang in Outbox of Outlook.

Exactly the same as SpeeDyLOCO I was having problems with my brand new Dell Inspiron 7580 and a brand new installation of Outlook (2016? - the latest version anyway). Whilst it would send emails from my POP3 accounts with BTInternet.com it wouldn't send any from Gmail or Yahoo. The Outlook test messages worked okay so it wasn't the password (although I switched off 2 factor authentication just in case although I knew it wasn't that as the same accounts with exactly the same settings worked fine still on my old Samsung laptop with the same version of Outlook). The messages from Gmail and Yahoo would just hang in the Outbox forever. Dell support were as much use as a chocolate teapot and just referred me to PC World whom I'd bought the thing from. PC World support were okay at first as I'd taken out the £8 per month support plan to help out the sales guy but cancelled it three days later. They didn't want to know after that and just told me to do a factory re-set. Muppets! I'd already done a LOT of searching the Internet for answers all to no avail, so then I got on to Microsoft Office support. One of their tech guys took remote control of my Dell and was mystified. He spent about 90 minutes and couldn't work it out. He upgraded my case to 'level 2' support and said they'd call me 'on Wednesday'. They didn't. A call did come the following Wednesday but only rang 5 times and they hung up before I could pick up. Aaaargh! And you cannot contact MS level 2 support yourself in any way. I tried back with the online chat at level 1 and as soon as they found out that it was escalated to level 2 already they didn't want to know. Promised that they'd call me back later the same day. Nothing. So after another 3 weeks or so, I got back onto another level 1 tech by online chat. He again took remote control and I didn't tell him it was already with level 2, I wanted him to have a try at least. And, you know what... he managed, after about an hour, to isolate it. He went through all the previous stuff like a new Outlook profile and, this time a new Windows profile. Neither worked but then he did a clean boot with only MS services running and EUREKA! the emails started sending. Which just left me to keep turning on the services that had been set not to load one by one until I found the offender. Actually I turned on half at a time and got there fairly quickly. And of course, the offender was SmartByte. I tried to update it... the Dell support site where you update your drivers had a new version of SmartByte with a date of just a few days ago on it, but on installing it, it was actually just the same version anyway. Another expletive from my mouth. Anyway, I uninstalled it with Revo Uninstaller Pro (although that's probably not necessary as it didn't find anything left over) but there was still SmartByte left in the start menu alphabetical list which I could right click on and get an uninstall button. I guess from the MS app store rather than a whole program. And then there were a couple of things in Location: C:\ProgramData\Dell\ that I searched for 'smartbyte' and deleted. And now everything works fine. I'm not sure if SmartByte will try to come back and I'm not interested in trying to see if all the other Dell software is up to date and compatible with it. I've never had a computer with SmartByte before and I've never missed it. Don't think I will now.

Re: Beware of SmartByte

Sorry but even with latest Intel Wi-Fi drivers updated and last version of SmartByte it's the same old story. It kills 50% of bandwidth. Let customers decide whether to install or not.

Would you mind sending us a diagnostic from your machine? We would like to take a look and see if there is any additional information that we do not currently have so that we can further investigate this issue.

You should have an application called "SmartByte Diagnostics" on your machine, accessible from the Start Menu, in the SmartByte folder.

Once you have located the application, please run the application, click Start at the bottom left and then, once it is finished, click Save to save the output file.

You can email us at smartbytesupport@rivetnetworks.com. Please attach the diagnostic to your email. Please do not copy and paste the contents of the diagnostic, as our email client may cut part of it off. Please send it to us as an attachment.

Thank you!

Thank you for your response. I sent the file by email. I hope will be helpful.

Re: Beware of SmartByte

I am having a similar problem. I don't have encountered or discovered an issue created by this program, but i remember to have uninstalled it before. And it has come back without me installing it. It doesn't seem to be a Dell's program, since its publisher shown in "Programs and Features" of Control Panel is Rivet Networks. So I believe it to be part of some other software's installer package, through which this program seems to be sneaking into our systems. If anyone has found a solution, could you please let me know? Many Thanks.

Re: Beware of SmartByte

When I try to uninstall SmartByte, a box pops up that says: "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." Suggestion for how to get rid of it?

Re: Beware of SmartByte

Smartbyte is like the technical version of herpes it never seems to want to disappear Completely. Everytime I try to uninstall it it comes back no matter what uninstaller I use. I'm a virtual DJ so smartbyte interferes with my program that I used to DJ with. There's days where I have to uninstall it two or three times. It can get really annoying

Re: Beware of SmartByte

I have a Dell Inspiron G3 and have found that SmartByte is blocking my email sending connection via Outlook and Microsoft mail. As soon as I kill SmartByte, my email is now able to send. After many hours on the phone with Dell support, one Tech finally found the issue. Wanted to share with this group. Don D.

Re: Beware of SmartByte

Dell downloaded Smartbytes 2.0.643 onto my Inspiron earlier this month. I use wired (not wireless) connections and it made no difference to my internet speeds. However I decided to follow Rivet's recommendation to update to the latest version 2.5.719. This reduced my internet download speed from nearly 40 to under 10. Rivet recommended changing my drivers but I decided to play safe and uninstall Smartbytes completely.This was not straightforward. When initially trying to uninstall the program I kept on getting an error message. I found I had to go into Services and disable Smartbytes Drives & Services and Rivet Networks Dynamics Bandwidth Manager; then restart my computer, then uninstall the program.
